ArcGIS Indoors Mobile not showing the same data as the Indoors Viewer

Description

ArcGIS Indoors Mobile may display a different occupant, unit, or other indoor data than the web-based Indoors Viewer. Users report one or more of the following:

• Indoors Viewer (web) displays current occupant information.
• Indoors Mobile displays outdated occupant information.
• Recent changes made to occupants, units, or other dynamic indoor data are visible in the web application but not in the mobile application.

Cause

The web-based Indoors Viewer and the mobile-based Indoors Mobile app can consume data from different map sources.

In the reported scenario:

• The Web Map used by Indoors Viewer referenced live feature services.
• The Mobile Map used by Indoors Mobile referenced an enterprise geodatabase (EGDB) feature class stored within the mobile map package.

Because the layer in the Mobile Map was packaged as a local feature class, any updates made after the mobile map package was created were not reflected in the mobile application (resulting in a 'stale' MMPK). The Indoors Viewer continued to display current information because it referenced a live feature service.

Solution or Workaround

Configure the mobile map package to reference the feature service instead of the enterprise geodatabase feature class

Note: 
Only use data from a feature service layer for data that updates frequently; otherwise, use local data for optimum app performance. Referencing online content is only supported for some Indoors feature layers. 

1. Open the Map used to create the Indoors mobile map package in ArcGIS Pro.
2. Review the data source of the problematic layer(s) by right-clicking the layer in the Contents pane and selecting Properties > Source tab.
3. If the layer references an enterprise geodatabase feature class, click Set Data Source and browse to the location of the feature service.
4. Select the feature service to change the data source.
5. Save the map.
6. Republish the mobile map package.
7. Update the Mobile Map Package section in the Indoors Viewer app with the republished MMPK.
